LATERAL ARM AND ROLLER BRACKET SUPPORT O Filed April l5, 1951 35 partsPatented `luly 12, 1932 uUNITED STATES PATENT OFFICE FREDERICK A. ANTON,F TOPEKA, KANSAS Application led April 13, 1931. Serial No. 529,600.

This invention relates to lateral arm awning constructions and has forits object the production of a construction adapted for installationwith modern store fronts particularly of the small specialty shops ofvarious kinds.

In construction of this character it has heretofore been impossible toinstal a standard lateral arm awning on account of the fact that notransom bar is used and the partitions between adjacent stores are sosmall and narrow that there is no point for the support of such lateralarm awning constructions.

There has been a continuous demand for awnings of the construction ofthe character above-mentioned, but, so far as I am aware, no one hasconceived of a construction whereby the strain of a lateral arminstallation can be safely carried by such store fronts.

The prime object, therefore, is to produce a unitary construction forinstallation on window display fronts, providing means carrying theoperative parts of the awning so arranged that unevenness in the windowfront may be compensated for by adjustment of the operative parts of theawning structure, and a construction which does not materially interferewith light passing through the window.

`With the general objects named in view and others as will hereinafterappear, the invention consists in certain novel and useful features ofconstruction and combinations of as hereinafter described and claimed;and in order that it may be fully understood, reference is to be had tothe accompanying drawing, in which Figure 1 is a broken and fragmentaryouter face view of a window front equipped with an assembly of lateralarm awning features, Vembodying the invention.

Figure 2 is an enlarged elevational view of part of the assembly. i

Figure 3 is a vertical section on the line III- III of Figure 2.

Figure 4 is a vertical section on the line IV-IV of Figure 8.

Figure 5 is a section on the line V-V of n Figure 3.

Referring to the drawing in detail, 1 indi- Cates a Istore front windowcasing, and 2 the glass-supporting frame.

- The awning assembly generally comprises a pair of brackets, a rollersuitably journaled and supported by the brackets, means to revolve theroller to wind and unwind the awning fabric, not shown, hangers on thebrackets and adjustable laterally lso that they shall stand in truevertical planes regardless oo of whether the same is true of the windowframe, lateral arms mounted on the hangers for swinging toward or awayfrom the window and adjustable up and down for providing variations ofpitch or inclination to the awning fabric when in spread or operativeposition. p

The brackets 3 are of inverted right-angletriangle form, Vand flangedand beaded for lightness and strength, and of scroll form at theirhypotenuse sides for attractiveness of appearance. f Said brackets aretted snugly in the upper corners of the window casing upon the top andside rails of the window frame and are detachably bolted thereto as at 4so as to distribute the strain on the frame, imposed by the assembly andincidentally stiften and strengthen said frame at the' points where thestrain is localized.

The awningroller 5 extends transversely of the window and is journaledat one end in a bearing bracket'a. At the other end the roller litsno-nrotatably in an angular socket of the shaft 6 journaled in a boxcomposed of separable members 7 and 8 bolted together as at 9 and to therespective corner brackets 3, at 10. A gear wheel 11 is secured upon theshaft 6 within the box and engaged by a worm 12 on an operating shaft 13depending from the box. f

Pivotally suspended from bolts secured to the respective brackets 3, arehangers comprising fiat bases 14, forwardly projecting necks 15 andtransversely extending tubular heads 16. Plates 17 and 1S fit against opposite ends of said heads for rotatable adjustment therein, and throughbolts 19 and retainingnuts 20 are employed to clamp said plates rigidlyto the heads to guard` against accidental rotary movement of the plates.100

- 'Ihe hangers have forwardly projecting tubular noses 21 provided withcircular sockets 22, and the hangers also have chambers 23 underlyingthe heads and arcuate slots 24 in the side walls of the chambers.Projecting into the chambers are screws 25 having spherical headsrotatable within said sockets 22 and held therein by protuberances 26 ofthe noses 21, and threaded on the screws 25 are collars 27 havingoppositely-projecting pins 28 engaging perforated lugs 29 projectinginto said slots 24 from the lower ends of plates 17 and 18. The plates18 have laterally-projecting perforated lugs 30 providing journals forvertical bolts 31 to which the inner or rear ends of the lateral arms 32are rigidly secured in any suitable manner.

From the foregoing it will be apparent that the operation of the screws25 will effect rotation of plates 17 and 18 and thus eect the raising orlowering of the outer or front ends of the said arms 32, and that whenthe desired tilting adjustment of said arms is attained, the nut 2O isscrewed more tightly on bolt 19 to retain the arms at the pitch desired,it being understood that the pitch of the arms determines the slope orinclination 0f the awning fabric (not shown) when in spread or operativeposition.

In the event the window casing is slightly out of plumb, the hangers canbe adjusted laterally to bring them to true vertical positions, byswinging adjustment on the upper or suspension bolts 33, the hangershaving arcuate slots 34 to accommodate these adjustments on the clampingbolts 35. To limit such adjustments the hangers have depending lugs 36equipped with set screws 37 playing between a pair of lugs 38 projectingfrom the cross brackets whereby the hangers may be accurately adjustedso that the opposite ends of the awning shall operate in synchronism.

From the above description it will be evident that while I havedescribed a construction embodying all of the features set forth asdesirable, it is to be understood that I reserve the right to make allchanges within the spirit of the invention and Without the ambit of theprior art.

I claim 1. A bracket for the support of window awnings formed along twoof its sides with a reinforced braced securing edge adaptable fordetachable engagement with the upper corner of a window glass supportingframe and spaced from the glass carried by said frame, said bracketbeing of generally triangular form with means adjacent its rightanglecorner to detachably support an end of an awning roller, the centralarea of said bracket being unobstructed for support-ing an awning arm inadjustable relation to the bracket.

2. A bracket for the support of window
